These issues may be caused by a poor harness connection or backed-out terminals inside the fuel tank, fuel pump module or flange assembly.

NOTE: If the fault is intermittent and cannot be verified during diagnosis, all of the checks in this TSB should be carried out and repaired as required. If a failure to the harness or individual fuel sender cannot be verified at any point during the diagnostic stage, both fuel level senders and the fuel pump module assembly should be replaced to avoid the possibility of a repeat repair.

Turn the ignition ON and observe fuel gauge operation.

- If the fuel gauge drops to “0” (empty), turn the ignition OFF, remove the connector and verify pin connections.
